Qualcomm have a system under development:

One issue that comes to mind is how will such systems cope with sleeping police men, or debris on the road e.g leaves or snow.

There is something appealing about the freedom and relative independence of filling up a tank and not worrying for 600 miles, rather than planning and booking (it may soon be necessary) the next charging stop.
If more cars are electric and booking a charge is essential, the logistics are painful to think about. If a vehicle books a charge, pre-pays, but is 30 minutes late, and the next available slot is 10 hours later .......

But probably well over 50% of the UK population will have difficulty charging overnight, unless you provide massive and very costly infrastructure to create charging points as effectively all parking spaces in public streets and car parks

Basically yes, from what I can see. Battery technology has advanced far enough & fast enough to make that technology pathway irrelevant as far as I can see.

Thinking about renewable energy, my mind is drawn to producer gas, generated from vegetable matter like wood chips or charcoal. During WW2 buses were to be seen towing producer gas trailers.
I once did a study into the feasibility of using wood to generate producer gas to fire a float glass furnace. My calculations suggested that a 7km square patch of eucalyptus in Brazil, cropped on a 7 year cycle, could sustain the process. Coppicing would be an alternative. I must dig out the original paper.
The Toyota Mirai is still in existence and being trialled by Greem Tomato Taxis in London IIRC........bruncher wrote:Is the hydrogen fuel cell car definitely written off?

Holy cow, that's a big chunk of productive land tied up to supply one facility providing just one of a myriad industrial products. Just illustrates the enormous scale of energy use and the infeasibility of fossil fuel substitution. Industrial society is necessarily a fossil fuel using society. The paltry energy flows from renewable sources are not able to scale to meet the immense demand from 7 billion people all trying to live like kings.

Approx 1.7 petawatt-hours from renewables?
I just can't get there myself: there are insufficient collectors of the diffuse forms of renewable energy, and manufacturing sufficient solar PV panels and wind turbines will require such massive non-renewable resource use that we must struggle to supply. We might prefer to burn the fossil fuels anyway as being at least achievable.

That's why although I have a very substantial portfolio position in upstream oil & gas it is all in short duration / low carbon production.
